Turns out they couldn't fit Dad in for an MRI last night, which means he may have to wait until tomorrow. He expects to spend at least another night in the hospital. Our prayer is that the MRI would provide the doctors with a clear indication of where this new pain is coming from, and of what the status of the old tumors is. It's apparently too soon to see the full effect of the radiation, which Dad completed last week, but hopefully the old tumors have begun to shrink. We still hope that the doctors will be able to formulate a new chemo strategy for Dad in light of the recent setbacks. On the upside, last week's blood tests indicated that Dad's white and red blood cell numbers are at good levels, so at least his body is still functioning there.
